Monitoring manner and device of gas medium trace component

摘要

Abstract Topic The case of ionization of measuring object material improvement selectivityPoint, raising the precision in the density measurement of the gas medium trace componentru. Solutions The trace volatile organicity chemical combination which is included in the gasThe online to analyze the thing making use of the laser, the content concentrationBeing the manner which is measured continually, the laser for choice excitation andMaking use of the multiple lasers where wavelength of the laser for dissociation differs, selectionThe photoionization with multistage excitation in order to improve CharacteristicOnly the organicity chemical compound which is the action and measuring object is ionized denselyWith by, the trace volatile organicity chemical compound which is included in the gasContent concentration is measured precision well.
